Franken ROC dataset

Description

This is referred to in the book as the "FR" dataset. It consists of 100 cases, 67 of which are diseased, interpreted in two treatments, "0" = conventional film radiographs, "1" = digitized images viewed on monitors, by four radiologists using the ROC paradigm. Often referred to in the ROC literature as the Franken-dataset, which, along the the Van Dyke dataset, has been widely used to illustrate advances in ROC methodology.

Usage

dataset03

Format

A list with 3 elements: $ratings, $lesions and $descriptions; $ratings contain 3 elements, $NL, $LL and $LL_IL as sub-lists; $lesions contain 3 elements, $perCase, $IDs and $weights as sub-lists; $descriptions contain 7 elements, $fileName, $type, $name, $truthTableStr, $design, $modalityID and $readerID as sub-lists;

• rating$NL num Array[1:2, 1:4, 1:100, 1] ratings of non-lesion localizations NLs

• rating$LL num Array[1:2, 1:4, 1:67, 1] ratings of lesion localizations LLs

• rating$LL_IL NA This placeholder is used only for LROC data

• lesions$perCase int Array[1:67] number of lesions per diseased case

• lesions$IDs num Array[1:67, 1] numeric labels of lesions on diseased cases

• lesions$weights num Array[1:67, 1], weights (or clinical importance) of lesions

• descriptions$fileName chr "dataset03" base name of dataset in 'data' folder

• descriptions$type chr "ROC", the data type

• descriptions$name chr "FRANKEN", the name of the dataset

• descriptions$truthTableStr num Array[1:2, 1:4, 1:100, 1:2] truth table structure

• descriptions$design chr "FCTRL" study design factorial dataset

• descriptions$modalityID chr Array[1:2] the modality labels

• descriptions$readerID chr Array[1:4] the reader labels
